Oceanography cussing the relationships between fabric and the engineer- ing behavior of clay. Van Olphen (1963) depicted in a descriptive sense the difference in particle arrangement of sedimentation from a peptized versus a flocculated suspension (fig. 9a, 9b). The main intent was to show that flocculated particles form a loose, voluminous sediment in contrast to a relatively dense sediment of closely packed particles formed from a peptized suspension. This would be equivalent to Lambe's flocculated versus dispersed fabrics respectively. Models were proposed by Von Engelhardt and Gaida (1963) de- picting voluminous clay structure (large aggregates) indi- cative of high salinity water and a more dense small aggre- gate structure characteristic of low salinity water. Van Olphen (1963) further described various conceptual models of possible modes of particle association (figs. 10a—g). His basic difference in the scheme of particle associations was the "dispersed" single particle (fig. 10a) versus the "aggregated" compound particle (fig. 10b) interaction. Van Olphen points out that three modes of particle association Figure 8.—^Dispersed structure with preferred grain orien- tation.

An essen- tial difference in the fabric concepts presented in 1958 was the absence of silt particles. Similar clay mineral arrange- ments were also shown by Schofield and Samson (1954). Other studies indicated that in sands permeated with clay suspensions, the clay plates orient parallel to the sand sur- faces (Brewer and Haldans 1957). Clearly, the presence of silt and sand mixed with clays would influence the overall arrangements of the clay particles in close proximit
